Warning and
Safety instructions
Read the operating instructions through before using this machine for the first time. This
way you will avoid the risk of accidents and
damage to the machine.
The tumble dryer is only intended for
drying fabrics, which have been washed in
a water solution, marked on the manufacturer’s wash care label as being suitable for
tumble drying.
There is a danger of fire with the
following, and on no account should
they be dried in this machine:
– Articles containing foam rubber, rubber or
rubber like materials.
– Articles which have been treated with
inflammable cleaning agents.
– Kitchen overalls which may be greasy,
fatty or impregnated with other residues.
Do not dry mops, floor cloths etc in this
machine if they contain substances such
as wax or chemical cleaning agents.
Damaged padded or filled fabrics (eg.
jackets or cushions) should not be dried. If
the filling comes out it could cause a fire.
Some textiles get very hot during drying
and there may be a risk of high
temperatures causing them to ignite in
exceptional circumstances. They should therefore be taken out of the machine as soon as
the programme has finished and as soon as
possible if there has been a power cut. Keep a
fire extinguisher near the machine.
The laundry must not be taken out of the
dryer before the drying programme has
finished, ie, the cooling down phase must
be completed.
If hot laundry items are stacked or packed
they could self-ignite.
Always make sure the drum is stationary
before reaching in to remove laundry.
Reaching into a moving drum is extremely
dangerous.
Repairs to the machine must only be
carried out by fully trained and qualified
service engineers. Unauthorised repairs could
be dangerous.
The electrical safety of this machine can
only be guaranteed when continuity is
complete between it and an effective earthing
system which complies with local and national
regulations.
It is most important that this basic safety
requirement is regularly tested, and where
there is any doubt the on-site wiring should be
inspected by a qualified electrician.
The manufacturer cannot be held liable for the
consequences of an inadequate earthing
system.
The machine is only completely isolated
from the electricity supply when it is
switched off at the wall isolator, or the distribution board circuit breaker.
Do not damage, remove or bypass the
safety features and controls on the
machine.
Where there is any damage to the controls
or to the cable insulation the machine
must not be used until it has been repaired.
Faulty components must only be
exchanged for original Miele spare parts.
Only when these parts are fitted can the
safety standards of the machine be guaranteed.
Do not touch the connecting pipework and
components. There is a danger of being
burnt.
Only use the machine if all of the
removable outer housing parts are in
place. This way any moving parts or electrical
components cannot be accessed.
Fire and Explosion risk
Never use or store benzine, petrol or petroleum based substances or any easily inflammable substances near the machine.
Peripel should not be stored near the machine.
Fire risk
Do not use the machine without the built-in
fluff filter in place. If the fluff filter is damaged it
must be replaced immediately.
A build-up of fluff could block the air flow
heating and ventilation, and impair the
efficiency of the machine.

Warning and
Safety instructions
Disinfecting and cleaning agents often
have compounds containing chlorides in
them. If these agents dry onto the steel surfaces, the residual chlorides will attack the
steel and can cause rusting.
If you accidentally spill an agent containing
chloride on the machine it should be rinsed off
with water and dried with a soft cloth.
To protect your machine from rust damage we
recommend only using chloride free
disinfecting and cleaning agents. If you are not
sure about a particular agent contact the
manufacturer for advice.
Do not use a high pressure cleaner or
water jet to clean the machine.
Caution If the tumble dryer switches off
prematurely during the drying cycle,
without the fault indicator light showing, this
could be due to high temperatures in the area
around the motor.
Heater limiters stop the tumble dryer.
In this case please check the seals and locks
on the machine door and the fluff filter.
Check the condition of the air inlet and air
outlet vents. If no damage is evident to any of
the parts checked, the dryer can be re-started.
If the fault occurs again, call G3 Systems.
All personnel working with this machine must
be fully trained in all aspects of its use and
safety.
Keep these operating instructions in a safe
place.

Before using for the first time
Preparing the laundry
Before using for the first time
Wipe the inside of the drum with a soft dry
cloth before loading the drum with laundry.
Preparing the laundry
Sort the laundry according to fabric type and
weave in order to achieve an even drying
result.
Not all textiles are suitable for drying in a
tumble dryer. Please pay special attention to
the manufacturer’s instructions on the wash
care label.
Significance of symbols:
= Dry at normal temperature
q
= Dry at low temperature
r

s
Articles made from pure wool and wool
mixtures tend to become matted and shrink.
They should not be dried in a tumble dryer.
For greater economy dry a full load.
Underloading is uneconomical. Do not
overload as this will impair the drying result
and the laundry finish.

The surface of pure linen is liable to be
roughened by tumble drying. Consult the
manufacturer’s instructions.
Important: Any laundry items with large metal
buckles, hooks, eyes, zip tags etc. should be
put into the dryer in a cloth bag (eg. pillowcase) to protect the drum from scratches and
dents.
Closed metal zips in garments may bridge the
sensor electrodes in the drum ribs causing the
drying process not to end or to end too late.
These items should be dried with the zips undone.
Damaged padded or filled fabrics (eg. jackets
or cushions) should not be dried. If the filling
comes out it could cause a fire
Some woven and loopknit materials tend to
shrink to varying extents depending on their
quality. This tendency is exaggerated by overdrying. Avoid the Extra dry programme for
such fabrics.
Sort the laundry according to the level of
dryness required. It is not necessary to sort
according to size.

Cleaning and care
Before cleaning disconnect the machine from
the power supply by switching off at the isolator or circuit breaker.
Disinfecting and cleaning agents often have
compounds containing chlorides in them. If
these agents dry onto the steel surfaces, the
residual chlorides will attack the steel and can
cause rusting. If you accidentally spill an
agent containing chloride on the machine it
should be rinsed off with water and dried with
a soft cloth.To protect your machine from rust
damage we recommend only using chloride
free disinfecting and cleaning agents. If you
are not sure about a particular agent contact
the manufacturer for advice.
Do not use a high pressure cleaner or
water jet to clean the machine.
Cleaning the fluff filter
The housing, control panel and any plastic
parts must only be cleaned using a mild cleaning agent or with a soft, damp cloth and then
dried.
Stainless steel housing should be cleaned
with a proprietary stainless steel cleaning
agent following the manufacturer’s instructions
on the packaging.
Never use abrasive cleaning agents to
clean the machine.
If you are unsure about a particular product or
need further advice please contact
G3 Systems. See back page for address.
The following should be checked and if necessary cleaned once a year by G3 Systems:
The whole interior of the tumble dryer
The fins on the ventilation fan
Clean the fluff filter (5) at least once a day, depending on the amount of fluff that has
collected and when the Clean fluff filter indicator light comes on. Do not remove the fluff
filter and be very careful not to damage it.
If appropriate maintenance is not carried out
regularly the efficient running of the machine
may be impaired and operational faults representing a fire hazard can occur.

optimised to the field laundry application as
follows:
Simple selection from a suite of
programmes tailored to the types of fabrics
and materials to be laundered.
Provision to process bagged or unbagged
laundry.
Timed drying process – to be used for
BAGGED laundry. The default drying time
is set to 55 minutes although this can be
increased or decreased by the operator to
account for the field laundry conditions.
Sensed drying process – to be used for
UNBAGGED laundry. The default residual
moisture setting is 3% although increased
or decreased dryness settings may be
selected by the operator to account for
the field laundry conditions.
Mass of dry laundry per bag is typically
